Question : Robocopy output messages

Is there a source for determining what error messages in a robocopy log mean?

Below are two examples of error messages that I am receiving, and I would like to know what they mean so that I can find a solution.

2004/06/03 16:53:30 ERROR 32 (0x00000020) Time-Stamping Destination File \\server\d$\users\username\file name
The process cannot access the file because it is being used by another process.

2004/06/03 17:34:41 ERROR 58 (0x0000003A) Copying NTFS Security to Destination File \\server\d$\users\username\file name
The specified server cannot perform the requested operation.

Answer : Robocopy output messages

The first one means that the file is in use. Common if the file is an Outlook pst file, or other Office file that puts locks on (Word, Access etc). Only drawback with running robocopy during the day.

Second one is a little strange. That is an error copying permissions. Both source and destination are NTFS? In the same domain?
Is robocopy running under a user context of someone who can write new permissions to a file on that drive or directory?
